|---|---|
| List the five ways of knowing something is true that we discussed in class. | 1. Experience 2. Intuition 3. Religion 4. Philosophy 5. Science |
| Define Science. | The methods of knowledge and knowing through experimentation observation and experimentation of natural phenomenon. |
| Discuss the categories of scientific knowledge: | -Foundation: Confidence in “The Scientific Method” data, reason, -Methods: Observations, Senses, Experimentation, Data Collection -Validation: Public - Objective/Systematic, Verifiable/Replicable, cumulative -School of Thought |
| Define Hypothesis | A hypothesis is an educated guess about how things work. Most of the time a hypothesis is written like this: "If _____[I do this] _____, then _____[this]_____ will happen." (Fill in the blanks with the appropriate information from your own experiment.) |
| In Science, can we ever prove a hypothesis is true (Y/N)? EXPLAIN. | No, we can never demonstrate the absolute truth of a hypothesis because we do not have perfect knowledge or control of all variables affecting that hypothesis. |
| What is a null hypothesis and why do we use it? | Null: only to disprove. In statistics, the only way of supporting your hypothesis is to refute the null hypothesis. Rather than trying to prove your idea (the alternate hypothesis) right you must show that the null hypothesis is likely to be wrong |

| What was William Gossett’s contribution to the world of statistics? | Logical revolution, Regression analysis |
